I have been writing about sovereign debt risk for some time. Japan, Spain, Italy and Portugal are all facing serious fiscal deficits and funding problems within a few years. But Greece may be the first country to hit the wall. In today's Outside the Box, we look at a short column by Ambrose Evans-Pritchard of the London Telegraph on the problems facing Greece. Greece will soon be faced with deciding which bad choice to make among a very small set of really bad, difficult choices.

And then we turn to a piece by Edmund Andrews in the New York Times about the funding problem facing the US. The US is going to have to borrow at a minimum $3.5 trillion in the next three years according to Obama administration officials, and it is likely to be much higher. And rates are likely to be rising. As Andrews notes "Even a small increase in interest rates has a big impact. An increase of one percentage point in the Treasury's average cost of borrowing would cost American taxpayers an extra $80 billion this year." If interest rates were at the same level as a few years ago, interest costs on the debt this year would be $221 billion more than they actually were.
